Cylinder -POLINI- P.R.E. 4 100cc - Ø = 52,0 - Piaggio 50 LC 2T

POLINI EVOLUTION P.R.E. 4 cylinder kit
At the heart of the cylinder kit is a newly developed cylinder, available in 70 cc or 100 cc flanged versions
and designed to be compatible with all flanged crankcases available on the market, as well as with Polini crankcases
.
Bore and stroke define a configuration designed for strong and full power delivery,
while the 5-port layout and bridged exhaust port ensure optimum gas flow and peak power.

Special attention was also paid to the completely redesigned cylinder head, which simplifies
installation on any scooter.
The side water outlet enables quick and easy installation.
The head, which is finished in the iconic blue Polini color, features a two-piece design with a special squish clearance and a specific compression ratio for each cylinder version.
These values are the result of precise internal geometry studies that are fully in line with Polini's philosophy of maximum efficiency.
